| Glow plugs - Maintenance & preventing issues |
|
Quote:Glow plugs don’t have a specific replacement interval and they are generally only replaced when they fail.
As a preventive measure, it is considered good practice to have them periodically removed and have the threaded section of the glow plug and the cylinder head cleaned and lubricated with a special ceramic grease that is suitable for very high temperature use.

Discovered via. Ian Richardson's thread:-

Thank-you Ian. This was news to me.
Next question; what does "periodically" mean ?

On one hand, if you broke a working GP trying to remove it you would have 2 reasons to kick yourself.
I guess you could move them a quarter of a turn (with torque wrench) every 2 years ? 3 years ?
Then 3 years later move it back the other way a quarter of a turn  (making notes in the service history which direction)

+1 Micky
Gone to the pain of getting them out you probably don't know when last replaced. So some nice new ones lubricated to easy removal if you need to.
